"During early Dec 2013, during one of the coldest winters in Michigan in 30 years, my furnace was having trouble keeping the house warm so I called Grand Ledge based Aire Serv to do a furnace check-up based on a coupon. They came out quickly and found a crack in the heat exchanger on my 20 year old furnace and shut it off, saying it was unsafe to run. Apparently it was about twice the BTU capacity than needed for the house and the constant shutting on and off had taken its toll. I was not the original owner so I am not sure why they over-sized the furnace.
I asked for quotes on a new furnace on the spot and they tried to sell me a $17,000 furnace and said no enough that the price came down to around $6,000. I really didn't like the very rehearsed sales pitch. It was so focused on how much better their warranty and service was compared to others that I knew it would be pricey. I really wish they had just laid out all their models and the features and prices and just let me pick my comfort level in features and prices rather than a sleazy sales pitch. I recommend you force them to skip the sales pitch and go straight to the facts.
I didn't have time to shop around and the house was very cold so I purchased one that night. They left some infrared heaters at no cost to help keep at least one room warm. I really appreciated that they offered to work a Saturday so we could have heat as soon as possible. They installed everything on time and as promised and were very nice. No complaints on the install experience at all.
I went with a two-stage Amana furnace at half the BTU of the previous furnace. It had no problems keeping the house warm during the rest of that very cold winter. I like the two-stage motor and have to set to always run on low when not heating or cooling. That keeps the air moving through the house for more even temperature and greater comfort - it really is noticeably better than on/off heating.
The exhaust venting couldn't go where they planned due to an unseen obstruction and so they had to vent it somewhere else that was a longer run and required extra work to get outside of the house. They did the extra work at no charge as promised.
Bottom line - they are an excellent company that did high quality work and kept all their promises and gave me an excellent product that fit my needs well and did it all on a tight timeline.
My only complaint is that since I was without heat, I feel I had to pay full price.But that is not their fault - that was mine for letting the furnace go bad and creating the emergency where I couldn't comparison shop.
When they sent me the post-installation survey, I sent a full response equivalent to what I have written here. They never responded back to me.
